Safety Information
This manual should be read in its entirety and all procedures completely understood before
installing or operating the unit, including all notes, cautions and warnings (examples below). The
CAUTION, WARNING, and DANGER statements that appear throughout this manual are
intended to provide critical information for the safety of both the service engineer and operator.
These statements also enhance equipment reliability. The following definitions and symbols for
CAUTION, WARNING, and DANGER as they are used comply with ANSI Z535.2, American
National Standard for Environmental and Facility Safety Signs, and ANSI Z535.4, Product Safety
Signs and Labels, issued by the American National Standards Institute.
Safety Guidelines
• Always use caution and common sense, especially when unsafe conditions or potentially
hazardous voltages are present.
• Repairs must be performed by qualified service personnel only.
• To reduce the risk of electrical shock, do not operate equipment with the cover removed.
• Never install telephone jacks in a wet location unless the jack is designed for that location.
• Never touch uninsulated telephone wires or terminals unless the telephone line is
disconnected at the network interface.
• Never install telephone wiring during an electrical storm.
Antistatic Precautions
This product may contain static-sensitive devices that are easily damaged by electrostatic discharge
(ESD). ESD occurs when a person whose body has built up static electricity touches a computer
component. ESD can cause computer components to fail. Take proper handling, grounding and
precautionary ESD measures installing parts or cards. Keep parts and cards in antistatic packaging
when not in use or during transport. If possible, use antistatic pads on floor and workbench.
When handling components, always use an antistatic wrist strap connected to a grounded equipment
frame or chassis. If a wrist strap is not available, periodically touch an unpainted metal surface on
the equipment. Never use a conductive tool, like a screwdriver or a paper clip, to set switches.
